We have investigated the magnetic properties of transition-metal oxide superlattices with broken inversion symmetry composed of three different antiferromagnetic insulators, [NdMnO3/SrMnO3/LaMnO3]. In the superlattices studied here, we identify the emergence of a relaxor, glassylike behavior below TSG=36  K. Our results  offer  the  possibility  to study  and  utilize  magnetically  metastable  devices  confined  at  nanoscale interfaces.
